The old piano in the corner of her living room beckoned to her. The rejection notification flashed in the corner of her screen. Emily sat down on the piano bench, the polished wood cool against her skin. The keys were ivory, and the wood had a worn and familiar feel.

She placed her hands on the keys, and the movement felt familiar, like breathing. She began to play a simple melody, a piece her grandmother had taught her. The notes, slow and deliberate, seemed to fill the room, and she felt a sense of calm.

She played the piece from beginning to end, and then, without thinking, she began to improvise, letting the music express the emotions she couldn't. Each note felt like a release, a way to channel her disappointment and fear.
